UNITED STATES PATENT ,FFICEO ITHlEL J. OILLEY, OF GRAND RAPIDS,MICHIGAN, ASSIGNOR OF ONEd-IALF TO GEORGE XV. CARPENTER, OF SAME PLACE.

COMBINED LATCH AND LOCK.

SPECIFICATION forming part of Letters Patent No. 366,646, dated July 19,18817,

Application filed January 10, 1887.

To all whom it may concern: 1

pie it known that I, ITIIIEL J. CILLEY, a citizen of the United States,residing at Grand tapids, in the county of Kent and State of 5 Michigan,have invented a new and useful Improvement in a Combined Latch and Lock,of which the following is a specification.

My invention relates to improvements in ordinary rim and mortise locks;and [O the objects of my invention are, first, to dispense with theextra bolt in use in ordinary door-locks for the purpose of securing orlocking the door; second, to obviate the necessity of making a key-holethrough the door-stile; and, third, to provide a means of inserting thekey through the knob, so that it will act directly upon the catch orspring-bolt of the lock. I attain these objects by the mechanismillustrated in the accompanying drawings, in which- Figure 1 is asectional view of a lock showing the bolts 13 and G and the spring II,and an end View of the lever, shaft, eccentric, and key-hole in theeccentric. Fig. 2 is a sectional view of the lever, the bolt G, thespring-shaft, eccentric-rod with flattened space, hole in side thereof,knob, and keyhole in knob and eccentric-rod. Fig. 3 is a perspectiveView of the shaft, showing the position of the hole in the side for thereception of the bolt G, and the inclines or notches at one end.

Similarletters refer to similar parts th roughout the several views.

The plate A, the bolt B, the lever O, the shaft 1), and the knobsEconstitute the framework of an ordinary door-lock, and the constructionof the lever O, the shaft D, and the knobs E, and the eceentricrod F,the bolt G, the spring H, and the key-hole through the knobs constitutethe main features of my invention.

The bolt B is an ordinary catch or spring bolt, with arms, &e., by whichit is drawn back by the action of the lever G.

The lever C is constructed with two arms, b I), which hook upon lugs onthe arms m m of the bolt B, for thepurpose of drawing said bolt, as inan ordinary door-lock. On one side of this lever, and standing at rightangles with the arms, is a projection, c, which is provided with a hole,(I, for the reception of a pin or bolt, G, which hole stands directlyover the Serial No. 223,971). (No model.)

portion of the shaft D having a corresponding hole, j. The center hole,of the lever 0, instead of being square, as in an ordinary door-lock, ismade round, so that the shaft D can turn freely in it.

The pin or bolt G is fitted to work freely in the hole (Z in the lever Cand the hole j in the shaft D, and is thrown forward toward the shaft bymeans of a spring, H. This pin or bolt is rounded on the end next to theshaft, so as to allow it to pass over the holej in the shaft, whenforced back by the eecentricrod, freelyand without catching on the sidesofthe hole when the shaft is turned in drawing the bolt 13.

The spring H is supported by the walls of the lockplate, and is madeconcave on one side to correspond with the motion of the lever, as shownin Fig. 1, and is used for the purpose of throwing the pin or bolt Gforward toward the shaft into the hole j and against the eccentric-rod.

The shaft D, instead of being made square, 7 5 like an ordinarylockshaft, is round, and is fitted to work freely in the hole 9 in thecenter of the lever O, and is provided with a hole,

h, extending entirely th rough it length wise, for the reception of theeccentric-rod F, and is made square across one end, while the other endis provided with two notches or inclines, i, over which the pin in oneend of the eccentric-rod travels, for the purpose, first, of holding theeccentric-rod from turning independent of the 8 shaft when the door islocked, and, second, to indicate by the motion of the eccentric-rod whenthe same is thrown round to a proper position to lock or unlock thedoor. The opposite end of the shaft being cut offsquare, is made smoothfor the support of a spring, 0, on the eccentric-rod, and through oneside of the shaft is a holej, which is directly in line with the hole (Iin the lever, and arranged to receive the pin or bolt G. The walls ofthe shaft 9 5 contiguous to this hole are flattened to form a gradualincline, to facilitate the turning of the shaft past the pin of bolt Gwhen this belt is thrown back out of the hole j, by means of theeccentric-rod, thus allowing the shaft XCO to turn freely in the lever Gwithout drawing the bolt 13. The eccentric-rod F is made somewhat longerthan the shaft,and is fitted to work freely in the hole h in the shaft.One end of this rod is provided with a pin, n, fitted to work in'thenotchesor inclines i on the end of the shaft, and the other end of therod is provided'with a pin or shoulder, r, between which and the endofthe shaft is a spiral spring, 0, arranged to allow a slight endwisemotion to the eccentric and to hold the pin a in the opposite end of therod against the end of the shaft. Each end of the rod is provided with aslot or key-hole at p, for the reception of the key, and the center ofthe rod at q is flattened to form an,ccccntric for the purpose ofallowing the bolt G to enter the holej in the shaft and of throwing itback, for the purpose of locking and unlocking the door. The knobs E maybe made of any appropriate material. and are attached to the shaft D, bymeans of screws or other device,'in the ordinary manner.

The keyhole I is made in the center of the knobs, and may be providedinside of the knob with such guards, k, as the manufacturer may deemnecessary or advisable, to avoid duplication, and are so arranged thatthe key may be inserted in the knob and communicate directly with theslot or key-hole p in the eccentric-rod.

The key Jshould be made thin and Hat and arranged to correspond with theinternal con-' struction of the key-hole.

The pin n in the eccentric-rod should be so To unlock the door, insertthe keythrough i the knob, turn the eccentric-rod until the flattenedspace q stands toward the hole j in the shaft, and then turn the shaftuntil the bolt G enters the hole j, which attaches the lever G to theshaft, so that when the knobs are turned the motion will becommunicated, through the shaftDand lever O, to the bolt B in theordinary manner. a

To look the door, turn the eccentric-rod onehalf way round, or until theround surface at q stands toward the hole j in the shaft, which forcesthe bolt G back out'of the holej in the shaft and allows the shaft toturn freely in the lever 0 without drawing the bolt 13.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination, in a mortise or rim lock, of the plate A, the bolt B,and the knobs E, with the key-hole I in the knob, the eccentric-rod F,having 'flattened surface q, slots or key-holcs 19, pins or shoulders atr, and. spring 0, the hollow shaft D, having inclines 'i and holej, thelever 0, having a round center hole, 9, projection 0, with hole 01therein, and arms b, the pin or bolt G, and the spring H, substantiallyas and for the purpose set forth.
